A true atheist "lacks a belief" and that is a perfectly honest position to hold. However, the rabid atheists who argue endlessly that "there is no God" are taking the same leap of faith that the proselytizing Christians are.

A true atheist would state there is no God. One who merely lacks belief is generally defined as agnostic. Since you don't even grasp the basic terms involved you might consider just butting out since those who'd argue either side wouldn't listen to you anyway.

An atheist LACKS BELIEF in a god or gods.

An atheist needn't express a belief that "there IS NO god".

Take, for example, someone raised without a concept of gods. They are an atheist because they don't profess a belief in god.

Strictly speaking, EVERYONE is an "agnostic". From the Jesus freaks to the rabid "positive atheists".
